STOPPING DEVICE.

Application filed July 21, 1919.

To all whom it may concern:

Be it known that I, ALFRED PooANY, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inStopping Devices, of which the following is a specification.

One object of my inventionis to provide a device which willautomatically stop the rotation of a record after a selection has beenplayed and will stop the record in such position that the sound box andreproducing needle will be out of engagement with the will be stoppedwithout the usual harsh sound caused when the record slows up prior tostopping as is the usual result of stopping devices now on the marketwhere the needle is permitted to remain in engagement with the recordduring the stopping action.

Another object is to so construct the device of my invention that theactual stopping action of the record will begin to take place after theneedle has been moved out of engagement with the record so that therewill be no friction between the record and the needle when the beginningof the actual stopping movement between the parts takes place.

A further object is to make the parts of my invention of a durableandstrong construction and their action.

These objects, and other advantageous ends which will be describedhereinafter, I attain in the following manner, reference being had tothe accompanying drawings in which--' Figure 1 is a top plan view,partly broken away, showing my invention attached to a sound reproducingmachine and showing the parts in a setting position,

Referring to the drawings, 8 represents a turntable having a record 9thereon, and 10 represents a rotatable sleeve support upon which ispivoted at 11 a tone arm 12 having a sound box 13 thereon, said soundbox supporting a reproducing needlelt. The rotatable sleeve 10 andturntable are rotatably supported by a supporting structure 15 which canbe in the form of a cabinet of any of the usual constructions.

.A cap 16 includes a weight 17 which is provided with a hole 18 adaptedto be placed over the usual center pin 19 and rest upon the top oftherecord 9. A column 20 projects centrally upon the upper face of theweight 17 and this column includes a helical groove 21 which pitchesupwardly and blends or merges into a spiral groove .22

formed in the top face of the column 20. A

mounted directly upon the top of the weight 17. A positioning pin 24projects upwardly from the top of the weight 17, preferably at aposition remote from the spring strip 23 and is for a purposehereinafter to be described.

A collar 26 is rotatably mounted around the sleeve 10 and to this collaris hinged at 27 an arm 28. This arm 28 at its forward end has a rod 29screwed therein, said rod having a knurled head 30, whereby. it can beturned to vary its vertical position relatively to the arm 28. Aprojection 31 on the arm 28 is adapted to engage the outer surface ofthe collar 26 and limit the downward hinging movement of said arm 28upon said free end 25 of the collar. It will thus be noted that the tonearm 12 and arm 28 can be respectively raised on the pivot 11 and hinge27. A second arm 32 is positioned on the arm 28 and is pivoted theretoby a pivot 33. One end of the arm 32 has worm-teeth 34 formed thereonwhich. are adapted to mesh with a worm 35 journaled on the arm 28. Theworm 35 is capable of being rotated by a knob 36, but is prevented fromrelative longitudinal movement transversely on the arm 28 by beingmounted between lugs 37 which form part of the hinge 27, as clearlyshown in Figs. 1, 2 and 3.

I. wardly on its 7 clamped or seta depending lip 51 lever 45 is closerThe collar 26 has a lever 38 adjacent its bottom and positioned belowthe turntable 8. A pivot post 39 projects from a base plate 39 which issecured to the supporting struc ture 15 under the turntable 8 and thispivot 1 post forms a rotatable bearing for a plate 40. The plate 40 hasa brake shoe 41 thereon and an edge portion 42 which is arrangedecc'entrically to the axis of the pivot post 39 and forms a cam forpushing a latch 43 uppivot 44 out of engagement with a detent lever 45,said detentlever being rotatably mounted on the pivot post 39 andhavingone endof a spring 46 secured thereto, said spring being coiled aroundthe pivot post 39 and having its opposite end pressing against a v thebase plate 39*. The plate 40 has a notch or indentation 48 which isproduced partiallyby the eccentric edge portion 42 and by a projection49 which supports the brake shoe 41. IVhen the parts are in theirposition, as for example as is shown in Figs. 1, 4 and 5, the latch 43extends within the notch 48 and is held between the projection 49 andthe upper end 50 of the detent lever 45, the spring 46 endeavoring tomove the detent lever 45 from the position shown in Fig. 4 to theposition shown in Fig. 6. The plate '40 has which is adapted to beengaged by the end 52' of the detent lever 45, when the latch 43 israised by the eccentric portion 42 under certain conditions, and it willbe noted that the end'50 of the detent to the pivot post 39 than is theextreme outer portion of the'eccentric edge 42. However, when the partsare in the position for example as shown in Figs. 1 and 4', the spring46 will exert pressure on the detent lever 45 to cause the latter topress against the latch 43 so that the latch Wilhprevent cloclnvisemovement of the plate 40 and detent lever 45. The plate 40 has an arm 53adapted to be engaged and -moved by the lever 38, and a handle 54extends'- outwardly from said plate 40 to a position beyond theturntable 8, as shown in Figs. 1 and 2;

The arm 32 has a finger 55 projecting upwardly therefrom is adaptedunder certain conditions to be engaged by the tone lug 47 which is fixedon 1 taking arm 12, said tone arm being at such level as to pass overthe top of the arm 32 and engage the finger 55. V

In the operation of my invention, the arms 28 and 32 can be raised 011the hinge 27 to permit the record to be placed upon the turntable, afterwhich the arms 28 and 32 can be lowered and the cap 16 is placed uponthe record so that the center pin19 registers with the hole 18 in theweight 17 and so that the positioning axis of the centerpin 19 and therod 29. The tone arm is then moved so that the reproducingpin 14 engagesthe last playing groove of the record, and the arms 28 and 32 are thenswung toward the tone arm until the finger 55 engages the tone arm. Thefinger '55 is then manually held-to the tone r pin24 is in line with thev arm and the knob 36 is rotated until the rod 7 during the playing ofthe record; After the record has arm will engage the finger 55 and swingthe arms 28 and 32 until the rod 29-is embraced spring strip 23 and bythe free end 25 of the been completely played, the tone carried, due tothe spiral shape of said spring strip 23, into the'helical groove 21whlch Wlll cause the arms 28 and 32 to be swung upwardly on their hinge27 and also cause the tone arm to be lifted on its pivot 11 to disengagefrom the record. After the rod 29 reaches the top of the helicalgroove21, it will be carried by the spiral groove 22 on the top of the column20 toward the center or axis of the pin 19 and in so move the arm 53 ofV the'cam portion 42 to raise the latch 43' out of engagement with theend 50 of'the detent lever 45 and permit the spring 26 to swing thedetent lever and with it, due to the engagement of the end 52 with plate40 so as to move the brake shoe' '41 into engagement with the dependingflange 56 of the turntable 8 and thereby stop theturntable after thereproducing needle has been raised out of engagement with the record.

The handle 54 of the plate 40 can be operatcd to move the plate so as'topermit'the rotation of the turntable and to re-set the latch 43 betweenthe end 50 of the-detent lever 45 and the While I have'des'cribed'myinvention as a particular form, it will beunder stood that thevarious parts of my invention may be changed withoutf departing fromthe;
